Abstract: A method for encoding a sequence of control information bits comprising: generating a sequence of error detection bits based on the sequence of control information bits; generating a sequence of error correction bits based on the sequence of control information bits; and distributing the sequence of error detection bits and the sequence of error correction bits between the sequence of control information bits to form a combined sequence of bits, such that the bit order of the combined sequence of bits following the distribution enables an error detection check to be performed before or after a first error correction check bit.

Abstract: A method including determining a cyclic redundancy check (CRC) generator sequence defining a one to one mapping between a sequence of control information values and cyclic redundancy check (CRC) sequence values; and determining a combined sequence, the combined sequence formed by distributing the cyclic redundancy check (CRC) value sequence within the sequence of control information values, wherein the distributing the cyclic redundancy check (CRC) value sequence within the sequence of control information values is based on a selected part of the cyclic redundancy check (CRC) generator sequence.

Abstract: A method includes accessing information, and at least one of encoding or decoding the information using a parity check matrix based on a coding rate. A portion of a data part in the parity check matrix has been generated based on part or all of another matrix. Apparatus, computer programs, and computer program products are also described. The apparatus may be a wireless mobile device or a wireless network access node. A communication system may include one or more of the wireless mobile devices and one or more of the access nodes, each using a version of the method.

Abstract: Various communication systems may benefit from efficient encoding and decoding. For example, certain multiple-input multiple-output devices may benefit from efficient encoding and decoding while operating with two codewords. A method can include receiving a first codeword and a second codeword. The method can also include segmenting the first codeword and the second codeword to provide similar sub-matrix dimensions. The method can further include outputting similarly sub-matrix dimensioned code blocks of the first codeword and the second codeword as a first code blocks and second code blocks.
